[0022] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0024] Moon pool gates are devices specifically designed for controlling the deployment and retrieval of sonar or other equipment, typically installed on the hull of automated vessels. Their design takes into account the complexity of the marine environment and the operational requirements of automated vessels, ensuring that sonar can be stably deployed underwater and quickly and accurately retrieved when needed. The structure of a moon pool gate usually includes a deployment system, a retrieval system, and a control system. Through the coordinated operation of these systems, automated vessels can effectively complete sonar detection missions.

[0025] In practice, automated vessels slowly lower sonar into the water through moon pool gates to perform sonar detection or measurement tasks. The design of the moon pool gate makes the sonar lowering process more stable, avoiding unexpected situations caused by waves or currents. At the same time, the moon pool gate also ensures that the sonar maintains a good attitude and position during underwater operation, guaranteeing the accuracy and reliability of the measurement data.

[0026] To address the need for underwater equipment deployment and retrieval, this project builds upon the existing solution of manual mechanical control and semi-automatic electrical control with a sliding moon gate, enabling unmanned autonomous deployment and retrieval of platforms such as acoustic instruments, optical instruments, UUVs, and ROVs.

[0027] Regarding the aforementioned technologies, the inventors believe that while the industry has undertaken some automation work in the area of ​​automated deployment and recycling devices, there are still significant shortcomings, making it impossible to achieve fully autonomous deployment and recycling.

[0028] To achieve fully autonomous deployment and retrieval, this application provides an automatic push-pull moon pool door device that meets the requirements of a hoisting device.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses an automatic push-pull moon pool door device that meets the requirements of a hoisting mechanism. (Refer to...) Figure 1 , Figure 2 An automatic push-pull moon pool door device for a hoisting mechanism includes a base plate 1, a sealed hatch 11 mounted on the base plate 1, and a hoisting sonar 2 vertically mounted above the sealed hatch 11. The hoisting sonar 2 is placed outside the hull through the sealed hatch 11. A hoisting assembly 3 is mounted on the base plate 1 to drive the hoisting sonar 2 to move up and down. The hoisting assembly 3 is used to hoist the hoisting sonar 2. A drive assembly is mounted on the base plate 1 to control the movement and opening / closing of the hoisting assembly 3 and the sealed hatch 11.

[0031] The sealed hatch 11 is equipped with drive components on both sides for opening the sealed hatch 11. In some embodiments, the drive components can be hydraulic or pneumatic. The drive components are horizontally positioned and drive the sealed hatch 11 to move horizontally, thereby enabling relative communication between the interior and exterior of the automated ship. When the sealed hatch 11 is opened, the dipping sonar 2 located inside the automated ship can extend outward through the open position of the sealed hatch 11. When the dipping sonar 2 retracts from the exterior of the automated ship, the drive components drive the sealed hatch 11 to close.

[0032] A slide rail 4 is horizontally mounted on the base plate 1 and is fixedly connected to the base plate 1. The sealed hatch 11 is located on the slide rail 4 and is slidably connected to it. A detection and control component is mounted on the base plate 1 and is signal-connected to the drive component. A control center module is also mounted on the base plate 1 and is signal-connected to both the drive component and the detection and control component. The detection and control component detects the position of the sealed hatch 11 and transmits the detected position information to the control center module, enabling the control center module to control the drive component to move or stop relative to the hatch.

[0033] The detection and control module includes a position data detection component and an image data detection component. The position data detection component includes a first position switch and a second position switch. The first position switch is located on the edge side of the slide rail 4 and is activated when the sealed door 11 is fully open. The second position switch is located on the center side of the slide rail 4 and is activated when the sealed door 11 is fully closed.

[0034] A first position indicator light is fixedly connected to the base plate 1 at a position relative to the first position switch, and the first position indicator light is signal-connected to the first position switch. When the first position indicator light generates a position signal, the first position indicator light illuminates. A second position indicator light is fixedly connected to the base plate 1 at a position relative to the second position switch, and the second position indicator light is signal-connected to the second position switch. When the second position indicator light generates a position signal, the second position indicator light illuminates.

[0035] The image data detection component includes a camera located above the sealed door 11, and the camera is capable of detecting the real-time status of the sealed door 11.

[0036] A sensing signal processing module is also installed on the base plate 1. This module is connected to the detection and control module, and also to the control center module. The sensing signal processing module processes the data generated by the detection and control module and transmits it to the control center module for subsequent operations.

[0037] The control center module has two operating modes: autonomous control and semi-automatic control. Manual mode has higher priority than autonomous control. In autonomous control mode, it makes control decisions for the drive components based on information from the first and second position switches, cameras, and other sensors; in emergency response mode, it completes the control of the drive components. In semi-automatic control mode, it receives communication control commands from the host computer to control the drive components; it does not operate in manual mode.

[0038] The drive assembly is equipped with a manual switching button, which toggles between automatic and manual control modes. The drive assembly operates in two modes: in autonomous control mode, it receives commands from the control center module to control the transmission actuators; in semi-automatic control mode, it is controlled manually via buttons for automatic opening, automatic closing, and emergency stop.

[0039] A dry-end cabinet 6 is located on the base plate 1. The control center module and the sensing signal processing module are located inside the dry-end cabinet 6, thereby driving the overall system to operate. A shock absorber 61 is fixedly connected to the bottom end of the dry-end cabinet 6, and the bottom end of the shock absorber 61 is fixedly connected to the base plate 1. In some embodiments, the shock absorber 61 may be a vibration-reducing device such as a shock-absorbing spring or a damper.

[0040] The hoisting assembly 3 includes a mounting frame 31, which includes a vertically arranged vertical beam 311, the bottom end of which is fixedly connected to the base plate 1. A horizontal beam 312 is arranged at the top of the vertical beam 311 and is fixedly connected to the vertical beam 311. The hoisting sonar 2 is located below the horizontal beam 312. A fixed pulley 32 is rotatably connected to the mounting frame 31, and a hoisting cable 33 is attached to the fixed pulley 32. One end of the hoisting cable 33 is fixedly connected to the top of the hoisting sonar 2, and the other end of the hoisting cable 33 is equipped with a winch 34. The roller end of the winch 34 is fixedly connected to the hoisting cable 33. By rotating the roller end of the winch 34, the hoisting cable 33 is wound around the roller end. The rotation of the roller end of the winch 34 then drives the hoisting cable 33 to move the hoisting sonar 2 up and down.

[0041] A slide rail 4 is vertically installed on the side of the vertical beam 311 of the mounting frame 31 near the sonar 2. A take-up head frame 41 is slidably connected on the slide rail 4. One end of the take-up head frame 41 is connected to the slide rail 4, and the other end of the take-up head frame 41 is fixedly connected to the sonar 2. The sonar 2 moves up and down under the drive of the hoisting cable 33. When the sonar 2 is in the extreme position, the take-up head frame 41 limits and buffers the sonar 2.

[0042] A riser platform 42 is vertically installed at the bottom of the slide rail 4. The top of the riser platform 42 is fixedly connected to the slide rail 4, and the bottom of the riser platform 42 is fixedly connected to the base plate 1. The highest and lowest positions of the retractable head frame 41 on the slide rail 4 can be adjusted by adjusting the height of the riser platform 42.

[0043] A limiting ring 5 is also provided on the upper surface of the base plate 1 outside the sonar 2. The limiting ring 5 is annular and coaxially arranged with the sonar 2. A support rod 51 is horizontally arranged on the outer wall of the limiting ring 5. One end of the support rod 51 is fixedly connected to the limiting ring 5, and the other end of the support rod 51 is fixedly connected to the vertical beam 311. The limiting ring 5 includes a first limiting part and a second limiting part. Both the first limiting part and the second limiting part are semi-annular structures. In some embodiments, the first limiting part and the second limiting part are fixedly connected by bolts, and when the first limiting part and the second limiting part are opened, the sonar 2 located inside the limiting ring 5 can be taken out.

[0044] A rubber pad is coaxially fixed to the inner wall of the limiting ring 5, and the rubber pad is located between the limiting ring 5 and the dipping sonar 2. It is used to limit the swaying of the underwater sub-unit when the platform is sailing.
